Answer:

$\large \boxed{\text{11 km/h}}$

Step-by-step explanation:

1. The situation after 15 min:

(a) Distance travelled by simulated biker:

15 min =¼ h

$\text{Distance} = \dfrac{1}{4}\text{ h} \times \dfrac{\text{20 km}}{\text{1 h}} = \text{5 km}$

(b) Distance travelled by Julian

Julian is 2¼ km behind the biker. The distance he has travelled is (5 - 2¼) km

5 - 2¼ = 5 - ⁹/₄ = ²⁰/₄ - ⁹/₄ = ¹¹/₄ = 2¾

Julian has travelled 2¾ km in ¼ h.

2. Julian's average speed

$\text{Speed} = \dfrac{\text{Distance}}{\text{Time}} = \dfrac{2\frac{3}{4}\text{ km}}{\frac{1}{4}\text{ h}} =\dfrac{11}{4}\text{ km}\times \dfrac{4}{\text{1 h}} = \textbf{11 km/h}\\\\\text{Julian's average speed is $\large \boxed{\textbf{11 km/h}}$}$

Decrease 340 minutes by 10%

Anvisha [2.4K]

Hey there,

To do this you need to work bout what 10% of 340 minutes is.
To do this do 340 / 10 = 34
34 is 10% of 340.
Now you should subtract the 10% from the original time.
340 - 34 = 306.
The answer is 306 minutes.

That was the long method. The short method is to use percentage multipliers.
To do this you do 340 x 0.9 = 306.

Either way you would get the same answer of 306 minutes.

Hope This Helps You!
Good Luck Studying :)
